SailChallenge was originally a program in C. It simulates a sailboat being navigated by an ANN (Artificial Neural Network). Now a Python "front end" has been created which invokes the compiled C program, and then captures the real time text output, converting it into an animation. A screen shot can be seen on our website. SailChallenge-2.0 is a free download from http://sourceforge.net/projects/annevolve. All source code is included, both C and Python. It will run on linux or Windows. Windows .exe files are available for Windows users who don't wish to compile the C code. Mitchell Timin -- I'm proud of http://ANNEvolve.sourceforge.net.
